' 1917. Serial No. 173,041.

To all whom it may concern:

Be it known that I, WiLLIAM M. MI'roHnLL, a citizen of the UnitedStates, and resident of Louisville, county of Jefierson, and State ofKentucky, have invented certam new and useful Improvements inAnticreeping Devices for Railroad-Rails, of which the following is aspecification.

The present application is a division of an earlier application, filedby me, March 31, 1917, Serial No. 158,791.

The invention relates to anti-creeping devices for holding railway railsagainst longitudinal movement, and seeks to provide a simple, eli'ectiveconstruction which is securely fixed to the rail, and which preferablyalso acts as a tie plate. The invention consists in the features ofimprovement hereinafter set forth, illustrated in the preferred forms inthe accompanying drawings, and more particularly pointed out in betweenthem, and then permit the engagethe appended claims.

in the drawing Figure l is a plan view of one form of the present inention;

Fig. 2 is a cross section on the line 2-2 of Fig. Fig. 3

and

Fig. 4.- is an end view, parts of the rail being shown in section on theline M of Fig. 3.

The form shown in Figs. 1 and 2 comprises a plate 1 inserted between thetie 2 and the base of the rail 3. The plate is provided, on its lowerface, with depending tic indenting portions 4, and, upon its upper face,with raised parts 5 upon which the base of the rail rests. The plate isalso provided with a shoulder or longitudinal rib 6 which extends alongone edge of the rail base, and the plate is provided with openings forreceiving spikes 7 which are driven therethrough into the tie, and theheads of which overlap thin edge portions of the rail base.

The plate or-anti-crceping device is held against movement by theengagement of the spikes with the tie and it is solidly and permanentlyunited to the rail base by welding or fusing the opposite edges of thelatter to the :nljacent portions of the plate. Preferably a fillet isfused from a steel rod by means of a suitable cry-acetylene torch and isa plan View of another form;

run into the space between the shoulder 6 and the adjacent edge of therail base, while the latter are heated by the torch nearly to the fusionpoint. Such a fillet is indicated at a in Fig. 2, and the metal bodythereof is integrally united to the adjacent portion of the shoulder andthe rail base. In a similar manner, a fillet b unites the opposite edgeof the rail base to the adjacent portion of the plate. y

In the preferred form shown in Figs. 3 and 4, the tie plate 8 isprovided at diagonally opposite corners with upwardly and inwardlyprojecting lugs 9, and at the other diagonally opposite corners, theplate is provided with holes for receiving retaining spikes 10. The lugs9, together with the body of the plate, form jaws which are arranged toembrace the opposite base flanges of the rail, the space between the awlugs 9 being sufficient to receive the base flange ment of the jaw lugswith the upper face of the base flange by twisting the plate in ahorizontal direction. I

The opposite edges of the rail base are welded or fused to the adjacentportions of the plate and the inner ends of the hooks or jaw lugs 9,which overlap the base flanges,

are welded to the upper faces of the base flanges of the rail.Preferably fillets c are fused to the connected parts and extend alongthe edges of the rail base and along the ends of the hooks or j aw lugs,as shown.

Preferably also, these fillets, at diagonally opposite corners of theplate adjacent the spikes, are enlarged into bosses (Z, which extendupwardly and inwardly over the base flanges of the rail. The improvedanchor or anti-creeping device is thus securely united to the rail basewithout weakening the metal body thereof and efl'ectively 00- operateswith the tie to prevent creeping. In the preferred form shown, it alsoacts as a tie plate. i

It is obvious that changes may be made in the details set forth withoutdeparture from the essentials of the invention as defined in the claims.

I claim as my invcntion:

1. In anti-creepers for railway rails, the combination with a rail andits supporting cross tie, of a plate interposed between the tie and therail base and spiked to the tie.

messes mg a plate interposed between the tie and the base of the railspiked to the tie, said plate having lugs overlapping and Welded to theopposite ease flanges of the rail.

3. In anti-creeping devices for railway rails, the cembination with arail and its supporting cross tie of a plate interposed between the tieand the rail base and spiked to the tie, and metal fillets fused 0rWelded to the opposite edges of the rail base and to adjacent portionsof said plate, said fillets being extended upwardly over and Weldedtethe upper faces of the base flanges oi the re K In testimony whereel"l affix my signature.
